QHead,
So, I look at it this way. ivy baseball is extremely selective, but not all that complicated. It is about risk management. If your son is a genuine D1-caliber talent with 29-30 ACT then he has a chance (with a fair amount of risk) to be recruited by Ivys. If he is able to move that academic needle incrementally up, he reduces that risk ever so slightly, and their interest turns from casual interest to serious interest. A lot of this understanding your son's numbers and talent level relative to others competing for those same Ivy slots...there aren't many. There are a handful of folks on this board that started where your son's numbers project but ended up in the low 30s ACT and seriously recruited by Ivys. However, it is first extremely important for your son to a project as a D1 talent . That is what they are looking for, then their next question will be about grades and future plans. Good luck!
